Theron is nominated for Best Performance by an Actress in a Motion Picture - Drama for her uncanny portrayal of Megyn Kelly in Bombshell.

Speaking with ET's Kevin Frazier on the red carpet, she noted that she has not spoken with Kelly since the film came out.

"No, I haven't. I know she has seen the film and she tweeted about it, and I knew that it would be, it's going to be, it's hard for all of these women to relive it, but the importance of their story, I think they understand what that really means and the weight that it carries," the South Africa native tells ET.

Theron was surprised to hear that Gretchen Carlson, who is portrayed by Nicole Kidman in the film, was thankful for the movie.

"Wow, that is really nice because we have not really heard anything from her, so that's lovely to hear," the Oscar winner says.

When ET spoke with Theron in Los Angeles last month, she opened up how excited she was for fans to finally see the movie she filmed alongside other powerful female forces like Kidman and Margot Robbie.

"Excited. [It's] Nerve-wracking. It's a complex load of emotions," she explained. "I think we're all really excited to share this with the world finally. We're really, really proud of this film."
